Esophagogastric junction outflow obstruction (EGJOO) is an esophageal motility disorder characterized by increased pressure where the esophagus connects to the stomach at the lower esophageal sphincter. EGJOO is diagnosed by esophageal manometry. However, EGJOO has a variety of etiologies; evaluating the cause of obstruction with additional ...
Functional Lumen Imaging Probe (FLIP) is a test used to evaluate the function of the esophagus, by measuring the dimensions of the esophageal lumen using impedance planimetry. Typically performed with sedation during upper endoscopy, FLIP is used to evaluate for esophageal motility disorders, such as achalasia, diffuse esophageal spasm, etc. [1]
A ventricular outflow tract obstruction means there is a limitation in the blood flow out of either the right or left ventricles of the heart, depending on where the obstruction is. This can lead to cardiac hypertrophy, dilatation of the heart, and ultimately heart failure in some cases. [1] The right side of the heart is much smaller and ...
Oesophagogastric junctional adenocarcinoma. Oesophagogastric junctional adenocarcinoma (OGJ adenocarcinoma) is a cancer of the lower part of the oesophagus with a rising incidence in Western countries. [1] This disease is often linked to Barrett's oesophagus. The incidence of OGJ adenocarcinoma is rising rapidly in Western countries especially ...
Gastric outlet obstruction (GOO) is a medical condition where there is an obstruction at the level of the pylorus, which is the outlet of the stomach.Individuals with gastric outlet obstruction will often have recurrent vomiting of food that has accumulated in the stomach, but which cannot pass into the small intestine due to the obstruction.
Different factors such as pulmonary stenosis can also contribute with the right ventricular outflow obstruction. During tet spells, a decrease in systemic vascular resistance or an increase in pulmonary resistance would be physiologically observed. The main anatomic defect in TOF is the anterior deviation of the pulmonary outflow septum. [10]
Rastelli procedure. The Rastelli procedure is an open heart surgical procedure developed by Italian physician and cardiac surgery researcher, Giancarlo Rastelli, in 1967 at the Mayo Clinic, and involves using a pulmonary or aortic homograft conduit to relieve pulmonary obstruction in double outlet right ventricle with pulmonary stenosis.

Specialty. Cardiology. Absent pulmonary valve syndrome (APVS) is a congenital heart defect that occurs when the flaps of the pulmonary valve do not develop or are severely underdeveloped ( hypoplasia) resulting in aneurysms (dilation) of the pulmonary arteries and softening of the trachea and bronchi ( tracheobronchomalacia ).
